LATGHING AEEANGEMENT EOE noons on` WINDOWS.

To .all whom t mag/concerns 1 Y I- Be it known that I, PETERFRANTZ,aoitizen-of the United States, andfresident .of Sterling,Whiteside County, Illinois, -have invented a certain newand usefulImp-rovement' in Latching Arrangements for'Doors o'rxWindows, lofspecication. n l f This f invention .relates Vto .latching devices for'doors and windows, .and .-inore 'particulafrly to. those involving theuse ofY bolts" for p securing the. upper or lower end ofthe' door,

or of the swinging window, or bothr thev top` and-bottom, inthe wellknown manner.

Generally stated,I the'object of the inv-en-` l tion is to providenovel; and improvedmeans for moving the boltfrom the latching -positionthereof, when. it is desired to open' the door or window, Yand wherebythe handle `by which'the door or window vis. opened and closed," may .beturned orV oscillatedf to frey lease the bolt fromiits lockingengagementwith the doorway, or whereby azplurality' of bolts may bethuscontrolled, depending rupon thecharacter ofthe door or window, orsimilar structure,i'1pon.which` the invention is employed. It isalso anobject to provide certain details and features of constructionandco-mbinations'tending/to inf'zreaser the general efficiency anddesirabilityl of a latching lbolt arrangement of this particularcharacter;

To these and 'other usefulends, the invention consists inthe matters`hereinafterl set forth and claimed, and as .shown in the accompanyingdrawings; in which,-

Fig. 1A is an inside 'elevationY of a'latching bolt .arrangement appliedto a swinging. door, involving the use' of'a bolt at'the top. andvanother one for thebo-tt'om of the door, involving the principle of theinvention.

i prises a vdoor 1 mounted to swing outward, yinany suitable ordesiredmanner. Latchingbolts having casings 2 are mounted at'y top andbottom of said'door on the inner surface thereof, andeach casing `isprovided with afsliding Vbolt 3, these bolts having their outer. endsrounded-or beveled at 4 to enable vthem to automatically slide over'thestrike piecev 5 or other" means for engage'ment with lfthe bolt,thereby to latch the door in closed position. Each bolt has a reducedportion Y6 forminga stem which slides in the guide formedlby `the endpiece? of theecasing2 of the latching bolt device, and a'coil spring 8is yapplied tofsaid stein 6, between the vshoulderl 9 and theV guide 7,whereby the .spring of each ylatching bolt device tends to keep the boltin locking position. Chains 10are`connected t0 the outer ends of thestems 6 of the latching bolts, and yby pulling on' these chains,` thesprings 8 of the two bolts will" be compressed, and the outer engagingend-portions ofthe bolts will'he disengaged from theirstrike pieces;whichlatter arepsecured to "the doorway in fixedY position Vin anysuitable orl desired manner. The handle chains`10, wherebyI to ncontrolthe .two 'latching bolts, comprises an inside grip or loopshapedhandle'. 11 which is fixed on a bifurcated member 12,y which latterextends through the opening 13 `formedin the door. This 'member112'tisheldin position for rotation,I but against endwise .'di'splacement, thebracketMwhich-isy secured to theidoory ing 17 will exert a pull on eachchain, thus releasing the latching bolts from their locking engagementwith thestrike pieces on the doo-iframe, so that' thel door can beopened by means ofV said handle. V Outside the door a similarh'andle 18Vis providved,iwhich is fixed on the outer end of lthe Vmember '19, thismember 'being bifurcated, as shown, to

.. receive the said member 12 in interlocking rotation of one handleengagement, whereby y The member 19 is held will turn the other.

, againstzendwisedisplacement by the bracket plate 20,"the latter havingan opening pro'- lviding la swivelsbearing 21 in which the member `19 isfreetoturn.. This bracketv 20 Y upon the circumstances.

is secured to the door by screws 22, as shown, and thus the two handlesare connected aX- ially, so that .turning of one handle will turn theother, but by removing the screws 15 and 22, the handles can bedisconnected from each other and from the door. y

Inside the door, the portion 23 of handle 11 is formed withdiametrically opposite notches 24 to engage a locking bolt 25 in thecasing 26, said bolt being controlled by the handle 27, in the usual orany suitable manner. By having the two notches 24, t-he arrangement canbe used either on a right or left door, and the bolt 25 will be'arrangedto engage one notch or the other, depending Thus, when the latchingbolts 4 are in locking engagement with their respective strike pieces onthe doorway, the door is held in closed position, and when the lockingbolt- 25 is in engagement with one of the notches 24, the outside handle18can be turned to unlatch and open the door.l The person inside of thebuilding can do this, of course, by operating the handle 27 to releasethe bolt 25 from its lock'7 ing engagement with the portion 28, therebyto permit rotation of the handle 1 1, and the consequent withdrawal ofthe bolts 4 from latching engagement with their strike pieces.

ln addition, the bracket 20 may have a lower portion 28 provided with anopening 29, and the handle 18 may have an opening 8O adapted to registerwith the opening 29, so that a padlock 31, of any suitable charac-V rter, may be applied to these two openings to hold the handle18 againstrotation. Vith this arrangement, of course, the doormay be locked fromthe outside, and may be unlocked from the outside thereof, by means ofsaid padlock. When the door' is closed from the out-side, the ,lockingbolt 25 can be withdrawn and held in its casing 26, so that it Will notspring into the notch 24 when the handle 18 is released andatter thedoor is closed. This leaves the door in condition to be opened, from;the outside, when the padlock 31 is unlocked and taken oit, for then byturning the handle 18 the two bolts 4 will be withdrawn from lockingengagement with the strike pieces 5, which arefixed on the doorway atthe top and bottom thereof.

rll`hus the rotation of the handle 11, or of theV handle 18, will serveto exert a pull on both chains 10, so that both latching bolts 4 will bedisengaged from latching engagement with their strike pieces 5, and thuseither handle 11 or 18 is adapted not only to be rotated to unlatch thedoor, but is also adapted for use as a. grip in opening and closing thedoor.

After the handle mechanism is unlocked, either handle is then simplyrotated to unlatch the door, and "without releasing the vhand 'fromeither handle, the door'is then opened in the desired manner. Also, whenthe door is closed, by means of either handle 11 or 18, the latchingbolts 4 are automatically pushed into their casings 2 by engagement oftheir rounded or beveled portions 4 with their strike pieces 5, andthenv the bolts spring into position behind these strike pieces, in themanner shown. Consequently, of course, the springs 8 of the two latchingbolt devices employed in this way at the top and bottom of the doorserve to hold the handle mechanism in normal position, for rotation ofeither handle is yieldingly opposed by the springs of the latching boltdevices, when the handle mechanism is not held against rotation by theordinary latch bolt 25, or by the ordinary padlock 31, as previouslyexplained. The entire latching bolt and handle mechanism by which thebolts are controlledis easily and inexpensively applied to the door, andthe construction of the handle mechanism andlatching bolts is such thatthey are adapted to be inexpensively constructed from metal, mostlysheet metal, thus reducing the cost of production. i

The screws 15 and 25 are covered by the handles 11 and 18 and cannot betaken out while the handles are locked in this position.
